The Defense Ministry reports Russia’s Sukhoi Su-24 bomber skidded off runway during the takeoff at the Hmeymim air base

A Russian Sukhoi Su-24 bomber skidded off the runway during takeoff in Syria on Tuesday, killing the entire crew, the Defense Ministry said.

The accident occurred at the Hmeymim air base, in the Latakia Governorate, when the aircraft was accelerating before takeoff. The jet was on a combat mission.

The Sukhoi’s pilots were named as captains Medvedkov and Kopylov.

“The plane’s crew failed to eject and died,” the ministry said, adding that no damage on the ground was reported. A technical malfunction could have been the cause of the accident, it said.

Sukhoy-24 jet crashed in Khmeimim Russian air base in Latakia (Mash).

Russian military jets are based at the Hmeymim air base and carry out airstrikes against terrorists of the so-called Islamic State and Jabhat al-Nusra groups.

Russian aircraft have been delivering up to 150 strikes per day against the militants near Mayadin in the Deir ez-Zor Governorate, the ministry said.

So far, Russia has lost 37 service men in the fight, including a Russian general who was killed in Deir Ezzor, ground zero for the military offensive. Russia also lost two fighter jets last year, a Mig-29 and an an Su-33. Both were deployed from a carrier off the Syrian coast.
